Growing up in the 50's and 60's, neither I nor anyone I knew had any knowledge of drugs. Then we declared war on it. Within two years, drugs were omnipresent. WTF. I can't be the only one who has seen this.
Yes, I have seen it as well... we must be the same age. It was the hippy era of the late 60's and early 70's that prompted many social changes. Some good, some not so good. Like, you, when I was young, I never heard of narcotics. But that all changed in college.. with Woodstock, hard rock, woman's liberation, sexual liberation, two income families, and a lot of other changes that were instigated by the baby boom.
Looking back I wish we could put a lot of those genies back in their bottles - but of course that is impossible. But this un-winnable, and very expensive "war on drugs" is a total waste of time.
I say this as a former alcoholic who spent a month in a detox treatment center with people who had a wide variety of addictions - from drugs to gambling to bulimia. Once you are an addict, you cannot stop without assistance. So people are going to get their drug of choice somehow, at any price. As the price goes up, so does the motivation for people to either produce it locally or import it into the country.
The only thing we, as a society, can do is to legalize drugs so we have some control over the quality, price, and distribution of narcotics. Plus we need more effective education and perhaps make addiction treatment more available. We can't stop the use of drugs until we start to stop addiction.
If anyone reading this has a young person in their house, there are two great ways to quickly educate them about drugs and alcoholic. First, take them to the local hospital emergency room on a Saturday night. Here they can see the battered wives and the people seriously injured from driving or simply trying to function while intoxicated and strung out. It is shocking. The second thing you can do is to take them to an AA or Narcotics Autonomous meeting and have them listen to the stories of how drugs and alcohol ruined their lives. This is a very effective way for young people to learn about the potentially disastrous effects that drugs can have on people's lives.
